Description

TECHNICAL FIELD

[0002] At present, the ideal scheme of battery pack heat management is to use liquid cooling mode to heat and cool battery pack, and its heating and cooling effect is much better than traditional natural cooling and air cooling mode. Among them, a common type of liquid cooling mode is a liquid cooling plate scheme based on coolant, which is characterized by multiple series and parallel channels arranged in the plate, and inlet and outlet ends are provided at both ends to realize the circulation of water.

[0003] The patent with the present publication number CN217788537U discloses a liquid cooling plate installation assembly and battery pack, which comprises a battery module assembly, a liquid cooling plate assembly, a heat conducting member and a first fastener. The liquid cooling plate assembly comprises a liquid cooling plate and a mounting bracket, and the mounting bracket is integrated on the liquid cooling plate assembly and directly connects the battery module assembly and the liquid cooling plate through the mounting bracket. On the one hand, the mounting bracket can improve the overall structural strength of the liquid cooling plate assembly, prevent the liquid cooling plate assembly from deforming when assembled with the battery module assembly, and ensure the assembly quality. On the other hand, only one mounting bracket is needed to fix the liquid cooling plate and the battery module assembly together, which reduces the assembly process, effectively improves the assembly efficiency and reduces the assembly cost. By setting the heat conducting member, enough heat exchange area can be ensured between the liquid cooling plate and the battery module assembly, the heat management performance of the liquid cooling plate is improved, and the liquid cooling effect of the liquid cooling plate on the battery module assembly is improved.

[0004] However, the liquid cooling plate installation assembly and battery pack in the above-mentioned technology still have the following problems: in actual application, only the liquid cooling plate is installed at the bottom of the battery pack, and its cooling effect is limited for the battery pack. The reason is that the battery pack is usually composed of multiple battery monomers, and heat is transferred between these monomers. Therefore, some battery monomers may overheat, while other battery monomers have relatively low heat. This uneven heat distribution makes it difficult for the heat management system to accurately detect, and thus the overheated battery monomers cannot be effectively cooled, which may eventually cause safety hazards.
